How to make (almost) anything.
Week 16. Applications and implications.
Work done in the Lab under the guidance of my remote Instructor to accomplish the weekly assignments.
Propose a final project masterpiece that integrates the range of units covered, answering:
What will it do?
It will display visual indicators for the user to control his breathing rhythm and fall asleep after a few minutes.
Who’s done what beforehand?
- Eunice Lee is a yoga instructor, she made a "Hourglas lamp for guided breathing".
- Anne Vlaanderen made a project called "Pensieve", to change the mood of the user with color lights and scents.
What will you design?
A fancy lamp: it's physical shape, electronics and embedded programming.
What materials and components will be used?
Materials: Acrylic for lamp windows, PLA for the structure, copper plate for circuit board.
Components: LED strips, pushbutton, resistors, capacitors, relay, diodes, battery, wires, switch, 5V AC adapter, jack and plug.
Where will they come from?
Acrylic from The Home Depot.
PLA spools from 3D Market.
Copper plate from Steren.
Components from Inteligencia Artificial.
How much will they cost?
